Mar 19, 8. I will try to reformulate the case.

Hello everyone, New to the Forum. Then you could use standard SPI. And the nF is the decoupling cap.

And this one I’d like to adapt to a 12Vdc installation. I will get the 93d46 layout soon. I think it would be helpful for me to find a simple application using a SPI. I am looking for a link or a simple application to be used in reading the data of a eeprom eepro 93C46 circuit used for counting the number and duration of activations of a 12V DC power source.

Mar 19, 9. I have given the actual pins translated from your pin nos.

The question here is as follows: Mar 17, 5. The circuit containing the IC should be re-usable as is. Your name or email address: Pin 4 of the IC goes through The rest of connections not related to this circuit. I suppose that 93c4 SPI in there was meant to write and read in the 93c Mar 22, Thank you for the corrections. Posted by kishore in forum: If I have a 93c46 in a circuit how can be read the memory content without being altered.

Mar 16, 1. EEprom Not reading data Properly Thanks Rama but this is what I get it: Do you already have an account? I have the circuit board with a 93c46 eeprom which through an 8 pin connector is linked to the main board.

It appears that you are reading mirror pins.

Also at using an Arduino eprom as well might be a possibility to test but I’ll need more directions for that. Either the existing board was designed to allow the contents to be read or it wasn’t. Thank so far to the Long Island guy. Mar 18, 7. Embedded Systems and Microcontrollers.

Quote of the day. The 93C46 is a memory element. Reading the data of a 93C46 eeprom Reply to Thread. Thank you for the reply. Mar 16, 3.

Feb 24, 11, 2, It was allowed for the content to be read but within a special application. Mar 16, 11 0.

I can not split the pins 3 and 4. Do you think should be another approach? It needs some sort of controller to use it as it works over a serial interface. The problem is still in the interface from 3 control pins to eeproom control pins of Arduino Eleven. Look up SPI for those details. I’m still waiting for some more suggestions. If not then more drastic measures will be required including a “vampire” connector that taps into the existing circuitry or desoldering and isolating the chip so that you can get to the signal lines without interference.

Mar 24, The 93c46 on the circuit board has the pin 5 and 6 connected through a 13,7 KOhm, and other connections: For the command streams sent to 93C46 all start, cmd or opcode, addrwhen they eepgom not multiples of 8 bits, then you can pad it up with 0 at the beginning.

Mar 17, 6. If you have to use this you need to use the resistors as in the AN, you need to write a bit bang SPI taking care of timing requirements! Mar 20,
